Hello!
Thanks for your entries. As you can see #49 is one of my favorites. There has just come another idea in my mind. Could you try to change the bitten off O to a version where the O is a cube and one corner is "flying away". For example that 3 brickets are flying ... Something like the pattern below, but more symethric ;) ..

I hope you understand what I mean ...
